IPWATCHD(8) System Manager's Manual IPWATCHD(8)NAME
ipwatchd - IP conflict detection tool for Linux
SYNOPSIS
ipwatchd --config config_file [--debug] [--test]
ipwatchd --version
ipwatchd --help
DESCRIPTION
IPwatchD is a simple daemon that analyses all incoming ARP packets in order to detect IP conflicts.
Default configuration file uses "automatic configuration mode" with "passive protection mode" and it should be the best option for most
systems.
Configuration mode applies to the daemon instance and it specifies how the list of network interfaces that should be monitored will be
obtained. In automatic configuration mode IPwatchD detects all network interfaces automatically and sets passive protection mode for them.
In manual configuration mode it is up to the system administrator to specify list of interfaces and protection modes in configuration file.
Protection mode specifies the action that will be performed when IP conflict is detected. In active protection mode IPwatchD protects your
host before IP takeover by answering gratuitous ARP requests received from conflicting system. In passive protection mode it just records
information about IP conflict through standard syslog interface.
IPwatchD also supports execution of user defined scripts. See ipwatchd.conf(5) and ipwatchd-script(1) for more details.
OPTIONS
The following options are supported:
-c --config
Specifies path to configuration file.
-d --debug
Enables debug mode. Debug information are recorded through syslog with "daemon" facility and "debug" priority.
-t --test
Enables testing mode that is useful only for debugging. In this mode every received ARP packet is considered to be conflicting.
-v --version
Prints program version to standard output.
-h --help
Prints short help information to standard output.
CONFIGURATION
See ipwatchd.conf(5) for more details.

PGPOOL(8) System Manager's Manual PGPOOL(8)NAME
pgpool - PostgreSQL connection pool daemon
SYNOPSIS
pgpool [ -c] [ -f config_file ] [ -F pcp_config_file ] [ -a hba_file ] [ -n ] [ -d ]
pgpool [ -f config_file ] [ -F pcp_config_file ] [ -a hba_file ] [ -m {s[mart]|f[ast]|i[mmediate]} ] stop
pgpool [ -f config_file ] [ -F pcp_config_file ] [ -a hba_file ] reload
DESCRIPTION
pgpool is a connection pool server for PostgreSQL. pgpool runs between PostgreSQL's client and server. Any PostgreSQL client can connect
to pgpool as if it's a real PostgreSQL server. pgpool caches the connection to the PostgreSQL server to reduce the overhead involved in
establishing the connection to it.
pgpool can also be used with two PostgreSQL servers for fail over purposes. If the first server goes down, pgpool will automatically
switch to the secondary server.
pgpool is typically started and stopped via system initialization scripts.
INVOCATION
pgpool [ options... ]
Starts as a daemon in the background (unless -n is given).
pgpool [ options... ] stop
Shutdown.
pgpool [ options... ] reload
Reloads the configuration.
OPTIONS -a path
--hba-file path Sets the path to the pool_hba.conf configuration file (default: /etc/pgpool2/pgpool_hba.conf).
-c
--clear-cache Clears the query cache.
-d
--debug Print lots of debug messages.
-f path
--config-file path Sets the path to the pgpool.conf configuration file (default: /etc/pgpool2/pgpool.conf).
-F path
--pcp-config-file path Sets the path to the pcp.conf configuration file (default: /etc/pgpool2/pcp.conf).
-h
--help Print a help message and exit.
-m mode
--mode mode Shutdown mode: smart, fast, or immediate.
-n
--no-daemon Foreground mode. Error messages go to stdout or stderr, which could be piped out to log processors such as logger(1) or
rotatelogs(8). To daemonize, explicitly invoke pgpool in background.
-v
--version Print version and exit.
